Title: System and method of providing a mobile station's service support information to a radio telecommunications network
Inventor: MINICHIELLO PAT
IPC: H04W68/12
Filed: 1997-11-04
Granted: 2007-05-08
Abstract: A system and method of ensuring that a called mobile station's expected service type matches a calling party's service type in a radio telecommunications network in which both voice service and data service are provided. A service code generator (51) in a serving mobile switching center (MSC)(22) generates a service code that indicates the calling party's service type. The service code is sent in a page (29) from the serving MSC to the mobile station (24), and includes the service code. An expected service code generator in the called mobile station generates an expected service code that indicates the called mobiles station's expected service type. The expected service code is sent in a page response (32) from the mobile station to a border MSC (26) that borders the serving MSC. The border MSC (26) extracts the expected service code and sends it to the serving MSC (22) where it is compared with the calling party's service code. If the service codes match, the call is connected to be mobile station. If the service codes do not match, the mobile station is denied access to the radio telecommunications network.

Abstract: The present invention is for providing a production method of a bead inductor, capable of preventing deformation of a metal coil or dislocation of the axis position of the metal coil by the injection pressure at the time of injecting a molten resin material from a gate. A coil is fitted onto a coil supporting pin provided on a first lower mold of a mold for injection molding in a cavity of the. mold for injection molding such that the inner periphery of the coil is closely contacted with the coil supporting pin. A molten resin material is injected into the cavity. Then, the coil supporting pin and the first lower mold are taken out from the molded product, and a second lower mold without a coil supporting pin is provided for replacement. A molten resin material is injected into the space which has been occupied by the coil supporting pin. After removing the hardened resin molded product from the mold for injection molding, the end parts of the coil are cut so as to be exposed.

Abstract: A signal processing apparatus according to the present invention includes a 2-dimensional conversion processing section, a 2-dimensional emphasis and attenuation processing section and a 2-dimensional smoothing processing section. The 2-dimensional conversion processing section maps an observation signal in a first coordinate system onto a second coordinate system to output a 2-dimensional converted signal.  The observation signal includes a detection object component and a noise component to be attenuated, the noise component being composed of a first noise component and a second noise component. The 2-dimensional emphasis and attenuation processing section attenuates the first noise component to emphasize the detection object component and outputs a 2- dimensional filtered signal in which the detection abject component is emphasized. The 2-dimensional smoothing processing section attenuates the second noise component contained in the 2-dimensional filtered signal, and outputs a 2-dimensional smoothing signal, whereby a detection object can be detected based on the 2-dimensional smoothed signal.

Title: Biometric certificates
Inventor: DULUDE ROBERT S
IPC: G06F21/34
Filed: 1998-05-08
Granted: 2008-07-29
Abstract: Biometric identification is combined with digital certificates for electronic authentication as biometric certificates. The biometric certificates are managed through the use of a biometric certificate management system. Biometric certificates may be used in any electronic transaction requiring authentication of the participants. Biometric data is pre-stored in a biometric database of the biometric certificate management system by receiving data corresponding to physical characteristics of registered users through a biometric input device.  Subsequent transactions to be conducted over a network have digital signatures generated from the physical characteristics of a current user and from the electronic transaction. The electronic transactions is authenticated by comparison of hash values in the digital signature with re-created hash values. The user is authenticated by comparison against the pre-stored biometric certificates of the physical characteristics of users in the biometric database.

Abstract: A junk basket comprises a sleeve sized to fit within a well bore. The sleeve has a bore therethrough, an internal latch at its top end for connection to a complementary retrieval tool having an external latch. A basket floor is movable axially in the bore between a first position intermediate the axial length of the sleeve, and a second position resting on a retaining shoulder at the bottom of the sleeve. In a well bore, the basket floor is supported at the first position, preferably on a retrievable bridge plug, and debris is collected in the defined volume above the floor. When the basket is lifted during retrieval, the basket floor falls to the second position, increasing the collection volume, loosening the debris and loosening the basket in the well bore for ease of retrieval. Further, a novel method of jointly deploying a junk basket and bridge plug results. The basket is connected to the plug and a setting/insertion tool passes through the basket's bore and through a port in the basket floor. Once the plug is set in the well bore the setting tool is removed. By lifting the retrieving tool with a predetermined load over string weight, the basket is sheared from the plug, a ball engages the port in the floor and the floor falls, loosening the debris and basket in the well bore.

Title: Composition and method of preparing microparticles of water-insoluble substances
Inventor: PACE GARY W
IPC: A61K9/51
Filed: 1999-03-29
Granted: 2008-12-23
Abstract: Compositions and procedures that yield sub-micron and micron-size stable particles of water-insoluble or poorly soluble drugs or other industrially useful insoluble compounds are prepared using combinations of natural or synthetic phospholipids, a charged surface modifier such as a highly purified charged phospholipid and a block copolymer coated or adhered onto the surfaces of the water insoluble-compound particles. The combination of charged surface modifier and block copolymer allows the formation and stabilization of the sub-micron and micron size compound particles - stabilized by the charged phospholipid to provide electrostatic stabilization and the block copolymer to provide steric stabilization - and therefore prevents these particles from particle growth, aggregation or flocculation.
